At first glance, this puzzle looks like a simple question about height.
Egg A falls 1 meter onto dry sand.
Egg B falls 2 meters onto a soft pillow.
Egg C falls 1 meter onto a thick carpet.
So which egg is most likely to crack first?
The key is that the height is only part of the puzzle.
What really matters when an egg hits a surface is how quickly the egg is stopped.
An egg falling from a greater height reaches a higher speed before it hits the surface.
That means Egg B is moving faster than Eggs A and C when they reach their surfaces.
In fact, ignoring air resistance, an object dropped from 2 meters reaches about √2 times the speed of one dropped from 1 meter.
So Egg B has more impact energy to deal with.
However, the pillow is designed to absorb and spread out that impact.
When Egg B hits the soft pillow, the pillow compresses and slows the egg down over a longer distance.
That reduces the sudden force acting on the eggshell.
So even though Egg B falls from twice the height, the soft pillow can protect it from a sharp impact.
Now look at Egg A.
It falls only 1 meter, so its impact speed is lower than Egg B’s.
More importantly, the dry sand can move and deform when the egg lands.
Instead of stopping the egg suddenly, the sand gives way underneath it.
The egg can sink slightly into the sand, which helps spread the stopping process over a longer distance.
This reduces the peak force on the shell.
That makes dry sand a relatively forgiving surface for a falling egg.
Egg C is also dropped from only 1 meter.
Its impact speed is therefore about the same as Egg A’s.
But there is an important difference between the two surfaces.
A thick carpet can provide some cushioning, but it generally does not deform as freely as loose sand or a soft pillow.
The egg still comes to a relatively sudden stop when it reaches the carpet.
The exact result would depend on the type of carpet, what is underneath it, the thickness of the padding, the depth of the sand, and how soft the pillow is.
So in a real experiment, these details could change the result.
But based on the conditions shown in the picture, the intended answer is Egg C.
Egg C has enough impact speed from the 1-meter drop to create a strong force, while its surface provides less energy absorption than the loose sand under Egg A or the soft pillow under Egg B.
The interesting trick is that the highest drop does not automatically mean the egg will crack first.
The surface underneath the egg is just as important as the height.
A soft surface increases the distance and time over which the egg stops, reducing the peak force.
A harder surface stops it more suddenly, which puts more stress on the shell.
So, based on the setup shown, Egg C — the egg falling onto the thick carpet — is the most likely to crack first.
